oam;naaienlscpleeiner 21, 1944,i serial 10,555,079 y y `'Ihepresent invention relates generally to pipes.

-More particularly theinventi'onrelates to that type of pipe which adapted for use in connection with smoking of tobacco and comprises-a bowl with a tubularistem leading-therefrom and inyadditiona mouthpiece which -has a longitudinal` duct and is"rem`ovably connected to the end ofthe stem that 1is remote from the bowl.

One object of the invention isto provide a pipeof this Atypewlriich is animprovement upon and Yhas certain advantages over previously designed pipes and is characterized by the fact thatthe mouthpiece 'has an extension which fits within the adjacentA end of the stemand has simple and novel-means^ for cooling the `smoke asit passes from the bowl to the mouthpiece and also collecting tar and other substances resulting from use of the pipe.

Another object of the invention is to providev a smokers pipe of the last mentioned character in which the extension embodies a longitudinal series of horizontal open ended holes which deiine compartments with cross-partitions therebetween and the partitions have centrally disposed aligned I apertures therein which serveserially to connect the chambers-so thatithesmoke` travels successively therethrough preparatory to entering the longitudinal duct in the mouthpiece.

Another object of the invention is to provide a smokers pipe `of the type and character under consideration in which .the mouthpiece extension within the stem embodies a longitudinal series ofespacedl apart openended bottom holes which are located at the bottom of the chambers `and form wells for I collecting .the tar, condensate, juices and other material resulting from smoking of the pipe; I i I I I r A further object of the invention is to provide a smokers pipe of the last mentioned character in which the portion of the stem that is adjacent the forward end ofthe extension has a sleeve-like projection which lits tightly within a central aperture in the forward end ofthe mouthpiece extension and `forms Va seal wherebythe liquid material which collects between the extension A and the stem is precluded from owing back into thebowl. f I i A still further object of the invention is to provide a smokerspipe which is sanitary, may be manufactured at a low and reasonable cost and ,a claims. (01.1'314210) I 2 o I y Theinvention `consists in the several novel features which are hereinafter set forth and are more particularly dei-ined by claims at the conclusionhereof.

`jThe pipe which is shown in the drawing constitutes the preferred form or embodiment of the invention. It is designed for use in connection with smoking of tobacco and as its principal parts or components embodies a bowl Ii, a compositestem 'I and a mouthpiece 8. i 5

The bowl 6 is formed of wood or any other suitable material and is adapted to be charged with tobacco.

The stem 'I projects laterally from the base of the bowl and consists-of a tubular part Bland a sleeve part I0. The tubular part 9 is preferably formed integrally with the bowl and embodies a centrallydisposed longitudinal duct II which leads from, and communicates with,` the bottom portion of the bowl interior. The rearward end of the tubular part 9, i. e., theend that is remote from the bowl; embodies a centrally disposed longitudinally extending open ended cylindrical socket I 2. The sleeve part IIJ of the composite stem 1 is formed of hard vulcanized rubber or any other suitable material. It has a cylindrical inner periphery and embodies at one end thereof an integral crosswall I3.` Such cross wall abuts against the rearward end of the4 -tubular part 9 of the stem and embodies an integral forwardly projecting stem-like part- I4 `which lits snugly within the cylindrical socket I2 Aand forms a removable connection between "the two partsS and I0 of thestem. In addition to the sleeve-like partI4 the crosswall I3of the sleeve part I0 of the stem embodies a rearwardly extending `projection I5. l This projection is aligned with the `stem-like part I4 and has the periphery or external surface thereof tapered away from the bowl E. Alongitudinal duct I6 is formedin the stem-like part I4, the crosswall` I3 `perspective of the sleeve part of I8. rIhe other end portion of the mouthpiece is in the form of an integral `cylindrical extensionV I9 which fits snugly Within the sleeve part IU L is of such length that its forward end or extremity abuts against the crosswall- |13@ ofthe sleeve part Ill of the stem. ',Ihecentral portion of the mouthpiece is cylindrical,V as shown in Figure 4, and is of greater diameter than the eX-= j tension in order to proyide an annular shoulder 2t which abuts against. the; adjacent end edge of the. sleeve part Ill. The; extension I9; embodies al longitudinal series ofy spaced apart, horizontal, open ended, cylindrical holes12-I'f and these areof but slightly less. diameter than theextension and form. smoke chambers 22y with cross,- partitions 23A therebetween. Thelforwardmost partition embodiesa centrally disposed,V outwardly taperedaperture-ZA in which the-tapered projection I5 fits snug-lll,v alsfShOW-ninflgures. Land- 2. l

The other crossrpartitions are provided with aligned, centrally disposed apertures 25; which serve` seriallytofconneci'.v the; chambers 221. The forward end of the duet I'i leads to, and, conrmunir-fates with., the rearwardmost: chamber 22. When suction is applied-to the mouthpiece-.85 in connection, with smokin-gl of the; pipe the smoke resulting from burning of the charge o-fptobacco inthe bowlr-,o-ws vtlrst through the duct I; I. in the tubular part 9` of the stem- 'l-,then through the duct lith then successively through the chambers 22.- andr finally through the duct I'If. DueV te the fact that' the partitions are formed by the cylindricall holes-2|; the surfaces thereof; that facethechambers 22 arevertically curved. When the smoke in passing through the chambers strikes the aforementioned vertically ourvedlsurfacesit tendstoswirl-,andflowoutwards into contact with the portionsl ofthe. sleeve part Ill that are.` at thel ends of. the holes 2i. As` a result of ist ist

contact of the smoke with suchportion-s of.4 the sleeve part I-Ilthe smoke is: cooled., In addition to the horizontal cylindrical holes 2| the entension; LS- of the mouthpiece 8 isprovidedwith a longitudinal series of. spaced.- apart, circulan-bottomholes` 26 and a longitudinal ser-ies of spaced apart circular top holesl il'. The bottom holes are open ended. IIhey lead from the bottom porrtionsof the-chambers 22 and dene wells in which collect the tar,l condensate, juices andV otherv liquid` material resulting from smoking' of the pipe. The top holes 2l are open ended and lead upwards from the upper portions of the chambers 22g to the superjacent or top portion ot the sleeve part I0 of the stem. In-connection with swirling of the smoke inthe chambers 22.. the top holes fore pointed out, flows from thebowlrst through sleeve part the ducts I I and I6, then successively through the chambers 22 and thence through the smoke duct I1 in the flattened end portion of the mouthpiece 8. During ow of the smoke through the chambers the liquid material, such as tar and condensate, resulting from smoking collects in the wells which are formed by the bottom holes 26 and the smoke, as the result of swirling within the chambers, is cooled by being brought into contacftj; side and; Lipper portion's of the 0. a resultof the' factthat the smoke ows successively through the chambers the smoke emanating from the mouthpiece 8 is (cool and free from foreign matter. When it is desired to clean the extension I9 the mouthpiece' isrv removed from the sleeve part I0 of the stemfl.

The herein described smokers pipe is sanitary and; may be produced or manufactured at a low and reasonable cost. Itfefectively and eiiiciently iuliills. its intendedipurpose and,Il dueto the construction andl design of, the mouthpiece extension,
